- Ben Marks: Marcel was great to deal with. Had a slight mixup with the order and the issue was solved within hours. Amazing service and highly recommended :-)
- Carmel Ellen: How wonderful it was to be able to receive immediate help in purchasing a telescope when completely lost in this area, and on a Sunday when the majority of shops are closed! I was extremely satisfied with help given by Marcel - patient, knowledgeable, and able to explain simply. I highly recommend Astro Dog Online, Marcel and their website. Look them up! They're worth your time!

DESCRIPTION
2" Kson 495nm Longpass Filter
Brilliant Fringe Killer / Semi-APO Alternative
- Yellow 495nm Longpass filter.
- Suppresses the secondary blue spectrum when using achromatic and half-apochromatic refractors (increasing image sharpness).
- For visual and photographic planetary observations.
- Enhances contrast between the belts on Jupiter.
- Increases contrast of the lunar and Martian surface.
- Multi-coated for max contrast, no reflections, scatter or dimming.
We can say a bit more about these filters. If you have an Achromat, these will significantly help with clarity and fringing as well. It allows a lot of the light through while still eliminating the purple fringing. There is also less of a color shift compared with the #12 filter. It may also darken your suburban sky.
Kson have managed to achieve extraordinary transmission, with a near complete transmission after the 495nm band, with over 50 layers of coating. You'll be impressed!
1.25" Version is also available.
